Detection and Quantitation of T-2 Mycotoxin in Rat Organs by Radioimmunoassay

摘要

A standard radioimmunoassay was compared with radiochromatography for the ability to detect unlabeled T-2 mycotoxin in organs from exposed animals. When 10% of HT-2, the only known metabolite that cross-reacts with T-2, was included and expressed as T-2 equivalents in the radiochromatographic detection, correlation between toxin detection in liver, spleen, and kidney by the 2 techniques was r = 0.98. An unknown metabolite was detected in heart extract by radiochromatography. Inclusion of this material in the T-2 equivalents detected by radiochromatography indicated a near-perfect correlation among all 4 tissues. Keywords: Assaying; Test methods; Reprints.
